By attain.

V,ingthis object thesickle isallowed to cut the grain at auniformheight, and correspond perfectly to the undulating surface of theground,without rackillg the reel, The invention lhas further for its object thefitting or securing of the reel-arms tu their shaft, whereby the-armsmay bereadily attached to the shaft and in a very secure manner.

'llo enable those skilled in the art to fully understand and constructmy invention, I will proceed to describe it.

A represents the main frame of a harvester, and B the plattorm,wliichhas the usual fingerbar and sickle at its front end. This platform isattached to the main frame A by means of a jointed connection, a", whichadmits of the platl'orm working freely up and down, so that the sicklemay conform to the inequalities of Ehe surface of the ground.

To the 'nein freine Aof the harvester there is secured an upright. O,the npner nant of which has a horizontal .forked erin, D, in which anupright pin, Ede lrteeh The pin E passes through two eyes, aib, in thearm D. The lower eye, c, is oblong, as shown clearly in Fig. 4, i

` so that the pin Enay.work or play laterally.

The upper eye, b,is not much larger in diameter than the pin; but it isconcave at its' upper part to lreceive 'the under side or lower part ofa bearing, F, which is at the upper end ofthe pin. (See Figs. l, 2, and3.)

c, at its outer end, the bearing F being'zbef. tween the pulley-c and ashoulder, houille shaftl G, as shown clearly in Figs. 1 and 3.. Theshaft G is tubular, having-a square hole through it for the reel-shaftIl to pass through, the portion of said shaft which passes through r theshaft G being also square and allowed te slide freely in the shaft. LThe opposite end ef shaft G is fitted in the upper end of an inclinedbar, I, which is attached tothe outer or grain end of the platform B.

From the above d'eseriplinn it will be seen thatthereel-shaft H cannotinterfere with the reen'ndnlntins movement of the nletferrn in.

.conforming to the irregularities of surface over which it passes, `forthe reel-shaft H is allowed to work .or slide freely in the hollow shaftG, and the bearing. F ot the latter, in conser qnenee of being attachedte the nin E, and the latter arranged as shown, is allowed to turn andworklike a universal or ballallfl-socket joint.

The reel-shaft H ispf iron, and upon it there are placed two metalheads, J J.v These heads J serve as a means for securing the arms e ofthe reelto the shaft H. 'Each head J is formed of two parts, f fr',andthese parts have each four radial grooved arms, g, (see Fig. 7,)which arms receive the ends ot' the reel-arms e, said. arms being ofwood. The two parts fff' uf the' headsare secured together by bolts Il;and the inner side of one part of each head is provided with lips orprojections i, which tit in the sides of the reel-armee, when the partsf f' are bolted together and prevent the arms from drawing out from theheads.v (See Fig. 6.) By this arf rangement the reel-arms e may besecured to, the reel-shaft H with great facility and very securely. `Theheads J are prevented from turning on the shaft H by means of screwboltsj, which passradially into onepart f or f ofeach head', and are securedfirmly against the shaft, (See Fig, 5.)

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
